Raman spectroscopic study of hydrous wadsleyite (beta-Mg2SiO4) to 50 GPa
Raman spectra of hydrous β-Mg2SiO4 (1.65 wt% H2O) have been measured in a diamond-anvil cell with helium as a pressure-transmitting medium at room temperature to 50 GPa. We observe three OH-stretching modes, a doublet with components at 3329 and 3373 cm-1, which decrease linearly with pressure, and...
